Hi all.
Tata Docomo 3G is very good. I am using it from Last 1.5 years and I am totally satisfied with its performance.
I am using a unlimited plan of 800 rupees per month and I am getting a very good downloading and uploading speed over this.
However the speed get little bit slower for 4-5 days in the last of every month but it is not as slower that you cannot serve the internet.
You can also get a good speed in your mobile while using wifi. It gives you a double benefit of internet on computer and inter net on mobile through wifi. I dont have to purchaase router to use wifi with the same. Really very good product of Docomo.
I really liked it.
